Specification of Letters Patent.

Patented May 30, 1916.

Application filed February 27, 1915. Serial No. 11,008.

i To all whomit may concern:

Be it known that I, HENRY JoNEs, a subject of the King of Great Britain,residing I at Fort Williams, in the Province of Ontario, Dominion ofCanada, have invented new and useful Improvements in Switches,-

of which the following is a specification.

'The present invention relates to an electric circuit maker and breaker,and mechanism for operating the same.

In carrying out my invention it is my purpose to provide an electriccircuit, such as a lamp circuit, with a circuit maker and,

breaker operated by a motor whereby the lamps may be lighted at adetermined time and likewise extinguished at a determined" time.

It is also my purpose to construct a device of this character in thenature of a clock having a revoluble disk thereon and hands rotated bythe operating mechanism of the clock, one of said hands being soconnected to the revoluble disk as to engage an electric contact whenthe disk is rotated a predetermined distance upon the face of the clockto light the lamp circuit, the second hand being also arranged to engagewith the disk in such a manner as to again actuate the contact to breakthe circuit and extinguish the lamps.

It is also my aim to provide a device of this character which shallembody the desirable features of simplicity in construction, cheapnessin manufacture and positiveness in operation. I

With the above and other objects in view, the improvement resides in theconstruction, combination and arrangement of parts set forth in thefollowing specification and falling within the scope of the appendedclaim.

In the drawings: Figure 1 is a front elevationof the improvement, Fig. 2is a rear elevation of the same, Fig. 3 is a longitudinal sectionapproximately on the line aczv of Fig. 1. Fig. 4 is a perspective viewof the circuit maker and breaker, the lamp circuit being shown indiagram, and Fig. 5 is a perspective view of one of the hands.

Referring now to the drawings in detail the numeral 1 designates amotor, the same, in the present instance, being in the nature of aspring motor, the mechanism being inclosed in a suitable framecomprisinga back plate 1 and a front plate 2, the said plates being spaced fromeach other through the medium of the-usual spacing sleeves through whichpassthe ordinary bolts.

The outer plate 2 is provided with the usual face or dial 3, the mainshaft 4 of the motor 'mechanism extending centrally through the saidface 3 for a suitable distance, and arranged upon the projecting end ofthe shaft 4 is a disk 5, the same having radially disposed marks ordepressions 6 arranged upon its outer face adjacent its periphery.. Thedisk 5, is also provided with a plurality of apertures or-small openings7, one of which being disposed adjacent each of the lndicating marks 6.The indicating marks as wellas the apertures 7 are twelve in number,corresponding with the hours indicated by the figures upon the dial 3. A

sleeve 8, of the ordinary construction, is arranged over the main shaft4, and extends through the central opening in the disk 5.

With my improvement I employ two hands indicated by the numerals 8 and 9respectively. Both of these hands are of a substantially similarconstruction, each having one of their ends provided with a sleeve 10which frictionally engages with the prosaid studs is adapted to beinserted through one of the apertures 7 in the disk 5, and to project asuitable distance beyond the inner face of the said dial. It should bestated that the dial 5 is disposed a suitable distance to the front ofthe face 3.

Arranged upon the frame of the motor, above theintermeshing wheelsthereof is the shaft 12 of the circuit maker and breaker. The shaft isjournaled in suitable openings in the front and rear plates of themotor, and the said shaft has secured thereon a sleeve 13 provided witha spring arm 14 which normally contacts with the inner face of the outerplate 2, of the motor, and serves to prevent the accidental rotation ofthe shaft .12. Arranged upon the'outer end of the shaft 12, whichprojects beyond the front face of the motor is a wheel 14, the samehaving its periphery provided with radially projecting pins 15, and oneof these pins is disposed within thepath of contact with one of thestuds 11 of one of the hands 8 or 9.

The shaft 12 of the circuit maker and breaker is insulated from theframe of the motor, and has its end Whichprojects beyond the rear plate1 of the motor frame, provided with a circuit breaker disk 16. This diskhas its rear face provided with a laterally extending pin 17, and ifdesired, the central portion of the disk may be formed of someinsulating material.

The numeral 17 designates an ordinary lamp circuit which may be providedwith a hand operated switch 18. One'of the wires,

indicated by the numeral 19 of the circuit 17 has its end provided witha wiper switch 20 which rests upon the periphery of the circuit breakerdisk 16, the second wire 21 of the circuit being also provided with aswitch arm 22 which is arranged within the path of contact of the pin 17of the disk 16.

The shaft 12 is of a sufficient-length to arrange the disk 16 a suitabledistance away from the rear of the motor frame, so that the windinghandle of the spring shaft of the motor may be manipulated withoutinterferring with'the disk 16, and the operation of the device may bebriefly described as follows: When it is desired that the lamps of thecircuit 17 shall be lighted ata certain hour and the determined time is,

'say, one hour distant, the pin 11 of the hand 8 is passed through theaperture 7 0 p0- site the figure 1 upon the dlal 3. It wi 1 be apparentthat when the motor revolves the 4 disk and consequently the hand 8, thepin 11 will engage with one of the pins or teeth 15 upon the wheel 14,rotating the shaft 12 a predetermined distance, the said distance beingsufficient to bring one of the contact fingers 17 of the circuit breakerdisk 16 into engagement with the spring switch 22. This completes thecircuit 17', and consequently lights the lamps of the circuit.

of the pins or teeth 15 of the Wheel 14, ro-

tating the shaft 12, in the same direction.

The rotation of the shaft will also rotate the disk 16 to bring'thepin-17, previously engaging with the spring switch 22, beyond the saidswitch. This movement will cause the switch 22 to lie between thecontacted pin and the adjacent pin 17 of the disk, thus breaking thecircuit and of course extinguishing the lamps.

Having thus described the invention, what 1 I claim 1s:

In a device for the purpose set forth, a motor, a disk having spacedapertures on the shaft of .the motor, a hand loosely car'- ried by theshaft and having a stud to be passed through one of the apertures of thedisk, a shaft journaled on the motor frame, a wheel having radiallyextending ins on the shaft and the said pins being isposed for contactby the stud of the hand, a disk on this shaft, said disk having spacedlaterally extending pins, and a member having switch arms one of whichresting in the periphery of the disk and the other disosed normallybetween two of the pins and in the path of contact with said pins.

In testimony whereof I aflix my signature in presence of two witnesses.
